[PATCH v2 2/2] dt-bindings: display: novatek,nt36523: define ports

[Krzysztof Kozlowski]

The panel-common schema does not define what "ports" property is, so
bring the definition to enforce the type.  All panels described by
binding are dual-link, thus require both ports.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski at linaro.org>

Changes since v1:
1. Rework to add ports to device schema, not to panel-common.
